See section 4 of Fox's contribution:

I was initially unclear about why you were running logistic regression on 
"censor", but perhaps you are trying to assess the non-informative 
censoring assumption? The R function that immediately comes to mind 
is glm( ...., family=binomial). Hmisc package also has lrm(...) and 
associated summary and diagnostic functions.
